Use this topic to
manage the nodes in your node groups
by viewing, adding or deleting the nodes in a node group.
Before you begin
Read about Nodes groups if
you are unfamiliar with them.
About this task
Make the nodes
that you organize into a node group enough
alike in terms of installed software, available resources, and configuration
to enable servers on those nodes to host the same applications as
part of a server cluster.
Node group membership must adhere
to the following rules:
- A node in a node group must be a managed
node.
- A managed node must be a member of at least one node
group. Initially,
all WebSphere® Application Server nodes
are members of the default node group named DefaultNodeGroup.
- If the node is on the z/OS® platform,
the node must be a member of
a sysplex node group. The node can also be a member of other node
groups that are not sysplex node groups.
- Nodes
on distributed platforms and nodes
on IBM® i platforms can be members
of the same node group.
- Nodes
on distributed platforms and
IBM i platforms cannot be members of a node group that contains a
node on a z/OS platform.
- Nodes that are in
different sysplexes must be members
of different node groups. Nodes that are in the same sysplex must
belong to the same node group.
